()ur invention has relation to apparatus for water quenching coke 1n coke ovens, and

designed to provide apparatus of this character which is simple and elij'ectivc in its operation] Furtherand more specific objects of the invention are to provide apparatus of this character, which is compact in form; which can be readily moved from one oven to another; which shall be automatic in'its operation; and in which the water is first used as a motive power for the device and is then used for the actual watering of the coke.

The nature of our invention will be best understood by reference to the accompanying drawings, which will now .be described, in which we have shown the preferred embodiment of the invention, it being premised, however, that various changes may be made in the details of construction and arrangement o'f'the various parts without departing from the spirit and scope of our invention as defined in the appended claims.

In these drawings, the numeral 2 designatcs a coke oven, a series of these ovens being shownin Fig. 1. Extending along each side of the series of ovens are parallel tracks rotary valves 17.

3 upon which is mounted a suitable carriage 4., which may be propelled along the said tracks by means of any suitable .motive power, such as ele tric motor Mounted upon each carriage -l and preferably, although not necessarily, arranged to travel on said carriage in a direction at right angles to the travel of the carriage (that is to say, toward and away from the ends of the ovens) is a car or support (3. Mounted upon each ear or support is watering apparatus A const ructed in accordance with our invention.

By means oil the carriages :l, the watering apparatus .i can be readily moved from one oven to another along the series of ovens.

'lhe watering apparatus shown upon the two cars or supports t; are similar to each other, and but one of them will be described in detail. This apparatus consists of a cylinder 7 having therein a piston 8, which is arranged to reci 'n'oeate within the cylinder and which iscarried by a hollow piston rod 9, which extends outwardly through a stalling-box It) at. one end of the cylinder. Connected to the projectinp end of the hollow rod 5) is a sprinkling head 11. The piston S is provided with a projecting hub 12 at each side, each of these hubs having therein a series of radial ports .13, the rod 5) being threaded, or otherwise secured in one ol' these hubs, as shown in Fig. 8. 'ithin the piston head and extending into both hubs is a rotary valve sleeve l4 also having ports therein, and arranged to control the ports 13, said. sleeve being so arranged that when the ports 13 ol one hub are opened, the ports of the other hub are closed and vice versa. The manner of actuating this valve sleeve will be described. hereinafter.

15 designates the supply pipe for the cylinder 7, said pipe extending longitudinally of the cylinder at one side thereof. This )i )0 i5 is connected with the end ortions of the cylinders by the short inlet )ipes 16, the admission to which is controlle by the Connected to.the pipe 15 is a water feed pipe 18 having the flexible portion 19. This flexible portion 19 is connected at its opposite end to the looped pipe. 20, having two parallel branches which extend above the cylinder and parallel therewith, and which form a support for the springler head 11 when the latter is extended into the furnace. For this purpose, the end portion of the hollow rod 9 to which the sprinkler head is attached is *the two similar ports 31 and 32.

connected with these looped pipes by the short rigid connection 21, as best shown in Fig. 9. In order to properly guideand sup port the looped pipe 20, as itis reciprocated into and out of the coke oven, with the.

sprinkler head, the cylinder is provided with a series of supporting and guiding rollers 22 and 23,'the lower branch of the looped pipe resting upon the rollers 22, and the rollers 23 extendin between the two branches of the looped pipe. Water is sup plied to the lower branch of the looped pipe by a connection at 24k 25 designates a valve shifting motor or engine which, in the particular arrangement shown in the drawings, is arranged trans versel underneaththe central portion of the cylinder 7. This motor or engine 25 (see Fig. 10) has a central piston chamber 26 with a valve chamber'27 at one side-thereof and a similar valve chamber 28 at the opposite side. The valve chamber 27 is arranged to communicate with the piston chamber 26 by means of the two orts 29 and 30, which lead into opposite end portions of the piston chamber; and the valve chamber 28 communicates with the piston chamber 26- by The ports 29 and 30 are controlled by the hollow rotary valve 33 mounted.in the chanr ber 27, and the ports 3i and are controlled by a similar valve 34 mounted in the chamber 28. y

3-1 is the inlet valv'e'"r"or the chamber 23 and 33 is the outlet valve for said chamber. As above described, the two valves 33 and 34: are hollow, and each is open at one end for 7 connection respectively with the inlet connection 35 and the outlet connection 36. The lnlet connect1on35 may conveniently form a branch oi the inlet pipe .18, and the outlet 4 connection may discharge at any convenient point. The valve 34: has the two ports 37 and 37* so arranged that when the port 37 is in register with the'port 3]., the port 37* will be out of register with the port 32. The only outletvalve 33 has the two similarly but reversely arranged ports, 38 and 39.

40 is a piston arranged to work in the piston chamber 26 and carried by a piston rod 41 which extends outwardly through a studing-box s2.

' Journaled in the side wall of each of the heads of the cylinder 7 and projecting inwardly into the interior Ohthesc heads is a tappet arm or linger 4-3. These tappet arms or fingers48 are arranged to be engaged by the piston tlnear the limits of its 'Connecting-crank arms eel ot'these shifts with tlie crank' arms 45 on the-projecting ends'of the ste1ns',l6 of the valves 33 and a iaaeo 39.- before described, are links or connecting rods 47. The two cranks 45 are connected by a link 47.

The projecting end of the piston rod ell which carries the piston all) is connected to a crank arm 48 of a longitudinally extending rock shaft 49. The ends of this rock shaft 49 are provided with cranks 50, connected each by a link'5l with a crank on the outer end of a shaft One of these shafts 53 is journaled in the end wall of each head of the cylinder 7 and carries at its inner end within the head a hook shaped crank arm 54-, best shown in Figs. 3, I and 8. This hook shaped crank arm, when actuated in the manner hereinafter described, is arranged to engage a pin or stud 55, secured to the valve sleeve 14 before described, and projecting outwardly through an elongated slot- 56 in one of the hubs 12. end portion of the valve sleeve carries one of these pins or studs 55, one for contact with the'crank 54 at one end of the cylinder 7 when the piston 8 is at the limit'of its contact with the crank arm 54 at the oppo- -site end of the cylinder 7 when the piston 8 'is at the end of its reverse stroke. ,The two pins or studs, together with the actuating arms 54 are so arranged, however,'as to cause the rotation of the valve sleeves 1.4 in opposite directions. each shalt 53 is also connected by. a link 57 witha crank 58 on the projecting end of the valve stem the adjacent admission valve .1? whereby said' valve will be controlled simultaneously with the movements of the crank arms I l The operation is as follows :"As the piston- 8 nears the limit of its stroke in one direconeof the links 47 to shift the position of the inlet valve 3 1 of the valve shifting engine or motor 25. This cuts oil the supply of water at one side of the piston 40, and admits water at the opposite side of said piston. By means of the link connection 47. between the stems of the two vvalves'33 and-34, the outlet valve 33 is also shifted. The relative action of these valves to admit water at one side of the piston 40 andexhaust it at the opposite side, will be readily understood from Fig. 10 without a detailed descriptionr The shifting of these valves and 34 causes a reverse movement of the pieithe links 51 and 54:, opens the admission valve list the end of the cylinder where the piston 8 now is, and closes the admission valve 17 at the opposite end .of the cylinder.- This movement of the rock shaft 49 also actuates the crank arm 54 to engage the pin It will be understood that each stroke in bne direction, and the other for The crank of ton l0,- thereby actuating the rock shaft it). This movement of the rock shaft, through or stud and thereby rotate the valvcslccve H- so as to close the ports 12% at: the right hand side of the piston, lookiiw at Fig. c, and open the ports 13 at the .lett hand side of the piston. The piston 8 now starts its reverse stroke and the water at the le it hand side of the piston exhausted through the ports 13 into the hollow piston rod 9 and thence to the sprinkler head ll Where it is discl'iarged. Vlhcn the piston 55% nears the other end of the cylinder '7, the in pet arm 43 at that end is actuated, therciy again shiftin the valves 33 and 34, and actuating the I'OCi shaft 39 in the reverse direction to reverse the inlet. alvcs l7 and also reverse the position of the valve sleeve l j. During the next; reverse stroke of the piston, the Water at the right hand side thereof is forced into the hollow piston rod 9 and is discharged at the sprinklenhciul ll. It will be seen, therefore, that when the apparatus is properly positioned with reference to the coke oven, and the operation is started, the piston 8 and the cylinder 7 nutomatic'ally continue to operate as a double iurtingmolor to force the water to the sprinkler head upon both strokes. The cold'watcr supply first passes through the looped supporting pipe 20, thereby preventing said pipe from burning out While it Within the oven, and then passes to the inlet pipe if). The water which forms the motive power for the motor is afterward utilized in quenching thc coke; and the only water lost is the compai'z'itivcly small amount which is exhausted from the alive 33 oi the valvc shifting motor. This water may be utilized if dccmcd advisable by piping it into the ovcn. or in other ways.

it will be understood that at each rccipio cation oi the piston 8, the sprinkler lu-ad ll will be reciprocatral within the ovcn over the bed of coke to bc quenched, being guided and supported 'in its movements by the loopcd supporting.pipe 20. it will be un' dcrstood by reference to Fig. 2 that. thc pur pose of providing a separatesprinkling apparatus at each side of the oven, or series of ovens, is to reduce the length of extension of thc sprinkler head into the ovcn, by making the sprinklerhead of each apparatus traverse approximately one-half the length of the oven. This avoids excessive ovcr-hang of the sprinkler head in its extended position. It will be obvious, however, that if desired, and particularly with some ovens, but one apparatus need be employed and the sprinklcrhcad be rovided with a suilicient extension to trave. substantially thclcngth of the oven. As above stated, however, this is not preferred, for the reason that it not only increases the overhang of the head, .ltllltit also increases the m'ccssary length of a yoke of the piston it will be obvious that various changes can be made in the details of construction and arrangement ot the parts. Thus, the several \alvcs employed may be oi. any suitable'charactcr; the precise means for shi't'tiug and actuating the valvcs can be changed, changes may be made in the manner of supporting and guiding the sprinkler head in its movements, and various other changes made. i
